A door control system for a farm implement with a storage bin having a discharge opening and a door movable between open and closed positions relative to the discharge opening, comprising:
- an arm having first and second ends;
- mounting means for pivotally connecting said second end of said arm to said storage bin such that said arm is rotatable between at least a first operating position and a second operating position;
- a controller connected to said arm and movable in relation thereto;
- a drive mechanism for moving the door between the open position and the closed position in response to movement of said controller when said arm is in any of said operating positions.
A farm implement comprising:
- a storage bin with a discharge opening and a door movable between a closed position covering the discharge opening and an open position exposing the discharge opening;
- and
- a door control system including an arm having first and second ends;
- a controller connected to said arm and movable in relation thereto;
- and a drive mechanism coupled with said door and said controller, wherein said second end of said arm is pivotally connected to said storage bin so as to be rotatable between at least a first operating position and a second operating position;
- and wherein said drive mechanism includes movable members arranged to move said door between the open position and the dosed position in response to movement of said controller when said arm is in any of said operating positions.
